What cause burned FET driver and FETS on 9920

[tom255]

I mean CAPS on ESC itself. On BK 9920 are 4 (samwha RD-series) 220uF 50V caps http://www.samwha.co.kr/upload/CAT_E/list_pdf1/RD.pdf Looks like they are more like Standard caps
i tought maybe change them to LOW-impendance bigger one like 330uF or 470uF or its unnecessary?

Edit: What a long read on "Quark fried, blown capacitor" thread learned lot and understood that LOW impendance is my friend it helps keep my ESC cooler and probably solve problems with weak brakes on 9920. I think i will buy 470uF caps and solder it to board.
